3 Claims.

This invention relates to a means or attach merit for a grain combine and it aims to provide a novel mechanism which will distribute the chaff It is particularly an object to provide such a and, clean it in a superior manner than heretofore.

To the under surface of grain pan, a mounting The more specific objects and advantages will become apparentfrom a consideration of the description following taken companying drawings illustrating an operative embodiment. In said drawings:

Figure 1 is a View showing a grain pan of a combine, in 'plan, with my improvements attached;

Figure 2 is an inverted plan view of the parts of Figure 1;

Figure 3 is a side elevation of a portion of the cornbinehaving my improvements attached; Figure 4 is a plan view of the main parts conzstituting the invention;-

Figure 5 is a sectional View taken on the line 55 of Figure 3, and Q Figure 6 is a sectional View taken on the line fi6 of Figure 3. I

Referring specifically to the drawings, a conventional grain combine is suggested fragmentarily at it? having an inclined grain pan at H. the combine at the plate or base i2 is fastened as at It. Suchplate has bearings 94 in which shafts I5 are journaled and which shafts at their innerends carry distributing blades it of any suitable shape and size which operate over the grain pan to distribute the received grain and chaff, of movement shown in dotted lines in Figure 1. Collars ii on the shafts i5 abut the inner surfaceof the plate 52 and from such shafts adjacent the free ends of the bearings M, are cranks It, and ill, the latter being central.

A fixed slide bearing or guide it is fastened as by brackets M to the machine It and it has a tubular portion 22 provided with open ends. Slidable in the tubular portion 22 is an equalizer rod 28 having a bar iifastened thereto from which a branch extends. Branch 25 has a rod or pitman 2t pivoted thereto at '27 and to the same moving to the extremes 1938, Serial No. 234,679 (Cl. 130 2 1) the crank 59 at 23. Another rod or link 29 is connected by a slot at 30 to the crank l9 and pivoted at its terminals as at 30 to the cranks l8.

brackets fastenedto a suitable part of the frame iii and adjacent'the lower end, such rod mounts a suitable weight 86 which is adjustable therealong by reason of the provision of a set screw 3'1. Rigidly and adjustably fastened to the rod 33 is a projection'or arm 38, a clamp 39 being used for the connection. Such arm 38 passes through the opening '32.

As a result of. the construction described, when the combine or machine i0 is transversely or laterally level, blades I6 extend longitudinally of the grain pan and vehicle. However, when the combine tilts laterally or outof the horizontal in a transverse direction, the parts 23, 24 and 25, will be slid laterally or transversely since therod the medium of the rods 26 and the blades I6 to either inclined position'shown, according to the directionof tilting laterally of the combine. I have found in practice that the blades serve to distribute the chaff and grain 'onto the sieve and shoe in an equalized manner.

Various changes may be resorted to provided they fall within the spirit and scope of the in-, vention. I r n I claim as my invention:

1. Apparatus of the class described comprising an attaching plate having bearings, shafts journaled in the bearings, distributor blades carried by the shafts on one side of the plate, cranks ex tending from the shafts on the other side of the plate, a mounting member, slidable means mounted by said mounting member, an arm extending from the slidable means, connections from the said'slidable means having a slot, and weighted means controlled by the level of a vehicle to which it is attached, the last mentioned means extending through said slot.

In combination with a vehicle having a and attaching shafts journaled thereon, distributing blades carried by the shafts on one side of the plate and operable over and relatively close to the pan for contact with material traversing the pan, cranks extending from the shafts on the other side of the plate, laterally movable sliding the latter to control operation of the cranks, and a weighted device controlling operation of the last mentioned means, said weighted device being controlled by the level of the vehicle.

3. In combinationwitha vehicle having a transverse inclined grain pan, and attaching plate, a shaft journaled in the attaching plate, a distributor blade carried by the shaft on one side of the plate and operable over and relatively close 10 to the pan for contact with material traversing the pan, a crank extending from the shaft on the other side of the plate, a mounting member, movable means mounted by said mounting member, an arm extending from the movable means, a connection from the arm to the crank, and weighted means controlled by the level of the vehicle to which it is attached, the last mentioned means being inter-connected with said movable means.
